今天又碰到的问题：Not able to place enough replicas

重启了n多边都没有效果。
删除之，发现你启动hmaster后该文件依然存在，删除后又恢复了。
干脆连着目录一起删除，ok
./hadoop fs -rmr/hbase/aaaa/8aab6d49ca2235530d7bf992dcb15e55
./hadoop fs -rmr/hbase/.META./1028785192
再次启动hmaser ok
./hbase-daemon.sh start master
jps查看 ok hmaster启动起来了。
咳，hadoop啊，想不暴力都难！！
该死，原来以为都ok了，同事测试的时候发现问题：
./hbase shell
list
可以看到表
可是扫描表的时候说表不存在。
立马想到是hbase本身出了问题。
果断修复
./hbase hbck
发现存在空洞不连续的情况。
./hbase hbck -fixMeta -fixAssignments
./hbase hbck -repair
修复完成后，再次./hbase hbck 发现还是有问题。
再一次./hbase hbck -repair
这次居然都ok了。
重新启动shell，扫描表。现在ok.了
重启hbase发现，hbase进程无法关闭，关闭客户端进程，ok了。
再次启动，突然发现包其中一台空间满了，晕，果断修复。
最后启动应用，居然调用都正常了。
真是峰回路转，变化万千。 心里暗暗骂一个，shit.
